ABSTRACT:
The status (`paid` or `not yet paid`) of each ticket to be validated is stored in the main memory of a computer, and a flag indicating whether the ticket is valid, the ticket amount and information necessary to locate the status information for the ticket is encoded into a validation number which is printed on each ticket. When the ticket is presented for validation, the encoded information on the ticket is read, forwarded to the computer and decoded into a status flag, the ticket amount and the status location. The status flag is then checked to determine if the ticket is valid; if it is, the decoded information regarding the status is used to locate the status information in the computer memory and change the status to `paid` so that the ticket cannot be cashed again.
